‘Poirot’

If you have never experienced David Suchet’s definitive portrayal of Agatha Christie’s Belgian sleuth, Hercule Poirot, it’s about time you settle into a comfy chair — perhaps with a cup of tea — and enjoy. N’est ce pas? The first of two new cases (“The Big Four”), adapted by Mark Gatiss (“Sherlock”), airs tonight. 9 p.m. Sunday, July 27, on KCTS (seattletimes.com/tvlistings).
